Firefox Support Forum

When typing comments on a web blog, after the spacebar is used, the first letter of the next word eliminates the previously typed space. So what I end up with is all words in a sentence running together. Tried other browsers and they work fine. Changed keyboard as well no joy. Typing is normal in applications like adobe, word, etc..... Only happens during Firefox use......... Uninstalled and reinstalled Firefox, also no help..... How do I fix ?

I've been using my banking site for many years on my desktop computer. Today the site comes up but when I try to log in I get a "404" error message. I tried logging in with Edge and there was no problem. I have deleted all my banking cookies on Mozilla and the result is the same. This is a major problem and I would appreciate any suggestions.

Hello,

When I close Firefox after the last update (current installed version: 112.0 x64 Windows 10), Firefox creates almost 200 processes (in the latest case 177), each using from 17 MB to 65 MB RAM (except one that is using over 200 MB - I guess the main one) using 100% CPU for about half a minute, and in that my PC is unusable - everything hangs. It takes a bit more time to close all of them.

Any ideas what could be wrong and how to fix it?

Thank you.

Hey folks,

i am facing issue with high CPU usage on firefox in completely different process other as visible in task manager than my actual process for firefox. is there something wrong with firefox or my system.

This separate process uses more than 60% of my CPU (AMD Ryzen 5 4600). If I close that process in the task manager nothing happens to my current firefox process and i can use firefox normally.

But everytime this separate process starts my system fans ramp up and CPU temps peaks to 70 degrees celsius. and i have to end that process to make it run normally. Thats a quite annoying process to do every time.

I am able to recreate this separate process by:

1. 1. Plug my system for charging
2. 2. I was working offline and connect to internet

both the times the separate process automatically starts and uses very high amount of CPU. I even left my system for 2 hours to keep that process running and complete whatever it was doing. but nothing happend. It continued to run for 2 hours also.

Please find a solution for this. I have already tried solutions provided in the forum:

• Restarting firefox
• Refreshing Firefox
• Enabling hardware accleration
• Clearing some user profile data
• Completely uninstalling firefox and deleting the residual files then reinstalling etc.

but nothing worked.

Hello,

I've spent several hours today trying to fix FireFox slow start up on my system. After start up (about 2 full minutes), everything works normally. The hardware is an ASUS A88xm-A MB, A10-6800K processor, 16G DDR3, runs OS and programs off an SSD. I worked through all the slow startup suggestions, ran memtest (0 Errors, 1 Pass), disabled all add ons, (even the OpenH264 video codec (I use the onboard HDMI, no graphics card)), turned off hardware acceleration, etc. When starting in troubleshoot mode, less than 30 seconds, (acceptable), but I really don't know where to begin with the "More Troubleshooting Information" when I look at the table generated by it. There have been no other problems to date with the system, and the long start-up time began with 20.04 Ubuntu (about a minute), then got worse when I upgraded to 22.04 to try to solve THAT problem. Currently running FF 104.0, and the update page says wait for a distro update if that is how it was installed. I believe 104.0 is the latest Linux 64b version though. All updates to the system are done as soon as I'm notified of them. there have been none since the upgrade a few days ago.

Any suggestions? Gotta get some sleep now... TIA, Dave

Hi guys! Stripe.com crashes FF. The site only displays about halfway down its homepage, then crashes FF. I've cleared cookies, all history, removed and reloaded FF, turned off tracking protection for Stripe at the address bar, lowered tracking settings to standard in FF, turned off hardware acceleration, and contacted Stripe directly. But they can't help with browser specific issues accept to offer standard solutions, which I already tried. Also, Stripe works fine in Chrome.

I'm using 1password extension, and for plugins: OpenH264 Video Codec provided by Cisco Systems, Inc. and Widevine Content Decryption Module provided by Google Inc. I deactivated both those plugins but no use. Ideas? Thanks! Ken

I cannot browser the following domains from just two days ago (2021/10/1). I received the error message I had typed on the topic "sec_error_expired_issuer_certificate".

https://www.liveinternet.ru https://warheroes.ru

I had checked somebody had the same error message several years ago and went to check the Certificate tab as mentioned in the following thread:

- Tools > Options > Advanced : Encryption: Certificates - View Certificates - Go to the Authorities tab. - Scroll down to the VeriSign section.

Now I don't know which Certificate are needed for "www.liveinternet.ru" and "warheroes.ru". Can any body help me to obtain the Certificate and found the old Certificate and delete it?

I am using firefox 12.0 but not willing to update it. Please understand I do not want to update my browser as a solution to solve the error messgae. I can't find any link to add exception when I visit these 2 domains (www.liveinternet.ru, warheroes.ru) ...

Can anybody help me as soon as possible. I visit www.liveinternet.ru everyday. Using another browser is annoying for me to browse liveinternet.ru...

The following image attached shown what problem I am facing...

This is the 3rd time I've posted here about crashing in the last month or so. I really do apologize for having to post again but I simply haven’t gotten to a solution. I really need to continue using Firefox as all the other browsers are significantly slower in my experience and I'm in the browser around-the-clock. I’d be willing to pay for customer support from Mozilla but they do not provide any type of support directly as most of you probably know.

Please review this link here to see all the steps I have already taken to troubleshoot the crashes.

I really thought that the crash reports I had would help me pinpoint the issue but it appears as though they’re not very helpful for those who can interpret them. If that’s not the case, I greatly appreciate it if anybody can dig through them to uncover some insights related to why I may be having frequent crashes (I'm willing to pay).

Thank you so much for any help.

I'm running 96.0.3 on a fully patched Win 10 Pro system - both O/S and programs. When Firefox is running I'm getting these pop-up error messages randomly with changing content. They stay on screen for some seconds and then go away. Message states it's from (via) 5.back2yard.biz. I put that in my hosts file and I'm still getting them. My network is a cable modem hooked to Xfinity and then cable connected to another fully newer patched router. All addresses are 10. range. I ran both a Malwarebytes scan and a Windows Security scan - both are clean.

I'm unable to upload a small image after a hour so I'll give up on that right now.

My problem,using Mint20.2-MATE, with FireFox92, is that FF92 shuts down whenever I minimize FF-i.e., totally down-does NOT appear in taskbar. I know I had the same problem years ago, and it was a simple fix. However, going through the "Help" sections in FF this time was no help. thank you for any suggestions.

I wondered several times why firefox recovers old tabs when it chrashed. now i see that in my profile folder/sessionstore-backups the file recovery.jsonlz4 is some days old (while i was using firefox in the meantime very often) and does not update frequently as requested by about:config browser.sessionstore.interval = 15000 (15s). - this folder or the files are not locked. i can delete/rename them, they are not re-created - there is no file sessionstore.* in the main folder of firefox profile while running firefox - i am using 102.4.0esr (32-Bit) on a company PC (could there be any restrictions?) - the file previous.jsonlz4 seems to be created correctly when firefox is closed normal (which is not my usecase, i want to restore up to date tabs after crashes) - i am not using a private window

do you have any idea?

Hi everyone,

lately I started experiencing a font-family-related issue. On certain websites the font-families/styles look broken. I tried troubleshooting the issue by myself without any luck. What I did so far was reset my Windows fonts to default, reinstall Firefox and look what font-families are loaded through the Inspect tool. If I opened the same web page in Chrome the font looks OK. Two websites the issue is most visible at - support.fiverr.com and gmail.com when someone replies to my e-mail.

Please find below a screenshot of what I mean

When downloading files, Firefox no longer remembers the directory path the file was previously saved to on a per-URL basis.

Previous Firefox behavior: #1. download file from website "aaaa.com" to a folder on your computer, "user/frank/companies/aaaa/". #2. download file from website "bbbb.com" to a folder on your computer, "user/frank/companies/bbbb/". #3. Now, go back to the website "aaaa.com" and attempt to download another file. Firefox used to present the previously used directory for this particular URL, in this case, "user/frank/companies/aaaa/" - but instead, now it presents the most recently used directory path, which was "user/frank/companies/bbbb/".

This issue has appeared before and the advice to fix it was to go about:config, search for browser.download.lastDir.savePerSite and make sure it is set at TRUE. I have done this, but the issue remains: Firefox no longer remembers saved file directory paths on a per-URL basis.

MacOS 11.6.6 (Big Sur); Latest Firefox (103.0.2) Attempts to fix: Safe Mode - issue still present; Refresh Firefox - issue still present

Is there any advice on how to fix this problem? - Thxs.

Upgraded to version 101.0 after getting the pop-up prompt and now every site I visit is taking at least twice as long to load and display compared to yesterday. (Even this support site!)

It has to be something in this release and not my connection, because:

• My mail client is completely unaffected and is behaving normally.
• I tried accessing the sites that were loading/displaying slowest using Opera, and they loaded as fast as they had in Firefox previously.
• Nothing else that uses my internet connection is working any differently than yesterday.

I also cleared the Firefox cache. No improvement.

It's not my add-ons because the only one I have installed is uBlock, which is recommended in various help articles here at the support site.

Nothing in the knowledge base has proven helpful.

Is anyone else having this problem? Is there some tweak I need to make in about:config to fix this? Or is this another case of "wait until the next release", yet again???

• I start Firefox. It works fine for a time
• Then, out of the blue, it says I have no Internet connection
• But, every other browser works just fine
• If I restart Firefox, it again works just fine, until it doesn't, again
• It just started doing this a few days ago
• I know everyone says this, but I didn't change anything other than the automatic update Firefox performed

Does anyone have a solution to this problem? Thanks.

why is FireFox 95 opening multiple windows on startup with Windows 10, Roboform, & Norton 360? FireFox is set to open a new tab, not new windows, so I do not know why it is doing this? I see lots of people asking this question, but there is no guidance online. What is up? This is causing FireFox to use way too much resources, and slows the computer.

Every time I play this online game at the site, Wormax.io, it will lag and/or crash the tab after a few minutes of playing. Occasionally, the site will take a very long time to load.

Here's my crash report: bp-4fd287ff-c2e1-4168-8e9d-ac1950211202

Hello,

since a week or so portal I frequently use - www.wp.pl started to work really slow. It crashes all the time, browser becomes inoperative, closes by itself, etc. It obviously happens to all pages, articles, services related to wp.pl. I cannot open a single page from wp.pl domain without issues. Before it was working completely fine, all of this started to occur for no reason. Also, it happens to wp.pl only. All other pages/portals/platforms function normally. I checked on different browsers - IE, Edge, Chrome and it works fine. I also cleared cache/cookies/browser history in Firefox and this didn't help at all. Therefore there must be something wrong with Firefox browser. Could you please investigate?

Thanks, Jacek
